The CRS is a Congressional "think tank" with a staff of around 700. Reports are commissioned by members of Congress on topics relevant to current political events. Despite CRS costs to the tax payer of over $100M a year, its electronic archives are, as a matter of policy, not made available to the public.

Individual members of Congress will release specific CRS reports if they believe it to assist them politically, but CRS archives as a whole are firewalled from public access.

This report was obtained by Wikileaks staff from CRS computers accessible only from Congressional offices.

In 1991, the Russian Federation inherited most of the Soviet Union's nuclear weapons, nuclear command and control system, and nuclear doctrine and employment strategy. It has altered both the nuclear doctrine and force structure in response to domestic economic pressures and its evolving position in the international environment.
